To minimize rotor wash hazards when establishing the approach path to a landing zone, which path characteristics are recommended?

• A. Approach from upwind crosswind with high hover.
• B. Direct, wind-aligned path with stable airspeed and altitude; coordinate with ground guides; limit bright light exposure to ground personnel.
• C. Random path with frequent altitude changes.
• D. High-speed, low-altitude approach.

Answer: (B)

Minimizing rotor wash hazards comes from choosing a path that keeps the helicopter’s downwash predictable and away from people and equipment on the ground. A direct, wind-aligned approach with stable airspeed and altitude gives the pilot the most control during descent and landing, because the wind helps smooth the hover and reduces crosswind gusts that can kick up debris. Keeping the airspeed and altitude steady prevents sudden changes in rotor wash, which lowers the risk of blowing ground personnel or equipment around. Coordinating with ground guides ensures a clear, illuminated path for the helicopter to settle into the LZ without surprises, and limits bright light exposure so crew members aren’t distracted or blinded by aircraft lighting. Approaches that come in from an upwind crosswind, wander along a random path with altitude changes, or fly fast and low tend to produce unpredictable downwash or hazardous debris patterns, increasing risk.
